Although shrink wrap film is widely known by most people, unless
you are in the packing and shipping industry you probably haven’t
stopped to think about its history and how it is used.Shrink wrap was first used to wrap buildings, yes, buildings by a
company called Global Wrap in the 1980s. Wrapping buildings with
shrink wrap is an effective method to protect the environment from
toxins caused by asbestos and lead removal. The company also used
shrink wrap to construct temporary shelters after an Iranian
earthquake in 1990. Shrink wrap is now used not only in continuing
to wrap buildings, but wrapping cars, electronics, X rated books to
protect the eyes of the little ones, beverage pallets, boxes,
crates, and is also used to combine objects together. The wrap
itself is made out of a high quality polymer that is designed to
withstand damage caused during transportation, damage from weather,
and from moisture. In order for the shrinking effect to take place,
heat must be applied. This is done with a heat gun for smaller
objects, and heat tunnels for larger products. The way the wrap is
designed with molecules arranged on the material in the same form
as a bowl of spaghetti. It is stretched out, and put in a frozen
like state. The material stays this way until heat is applied,
making it bounce back down to its original size. This is how the
shrinking affect is achieved.
